  • Color ultrasound system and method and device thereof for obtaining beam-forming line data
    Patent number: 10413279
    Abstract: The disclosure provides a color ultrasound system and a method and a device thereof for obtaining beam-forming line data. The method comprises: a processor sending a control command according to a currently triggered color ultrasonograph mode; the processor receiving the digital ultrasonic echo signal data obtained according to the control command, wherein the digital ultrasonic echo signal data is a digital signal obtained by performing analog-to-digital conversion on an analog ultrasonic echo signal; and the processor performing beam-forming processing on the digital ultrasonic echo signal data to obtain corresponding beam-forming line data. With the disclosure, the color ultrasound system hardware is simple in design and flexible, and resource conservation and cost reduction are achieved during technical update.
